Frames are important on a map because they clearly delineate the map's content, providing a visual boundary and containing essential map elements.
The Role of Frames in Cartography
Frames, often seen as simple lines surrounding a map, play a crucial role in its readability and overall effectiveness. They serve several important functions:
-
Clear Delineation: The primary function of a frame is to distinguish the map area from the surrounding page or background. This helps viewers immediately identify the boundaries of the geographic information being presented.
-
Content Containment: Frames are designed to contain all vital map elements, such as the map itself, legend, scale bar, north arrow, title, and any other supporting information. This creates a cohesive and organized visual presentation.
-
Visual Separation: On printed maps, frames often maintain a consistent margin width from the edge of the page. This separation enhances visual appeal and prevents the map content from feeling cramped or cluttered.
-
Neatlines for Organized Layouts: Within a larger map layout containing multiple map sections or insets, neatlines (a type of frame) are used to border each individual map area, ensuring a clear distinction between different data representations.
In essence, map frames help the reader quickly understand what geographical area the map is showing and organize the map's content in a logical and visually appealing manner. Without a frame, the map risks appearing disorganized or blending into its surroundings.
